IMPROVEMENT iN scoops AND slF-rERs.

The Schedule referred to in these Letters Patent and making part of the same.

.Nature mul Objects oft-hc Invent/ion. My improvements relate to the kcombination of an ordinary scoop for scooping flour, meals, grains,

spices, drugs, 85o., and of a sifter for sifting them, and

.separating dirt or foreign matter from the flour or grain or other matter required to be sifted.

Description of the Accompanying Drawing. Figure 1- is a vertical section; Figure 2 is a transverse section of the bottom por tion, showing the method of securing the detachable sieve; and t Figure 3, a front view of the sieve, detached. A is the bodyof scoop.- B is the sift-er. G is the sievecloth. D is the attaching wire-rod. EJE are small holes to receive wire-rod. F is the spring.- A' G is the thumb-knob. H is the handle of the agitator. K is the agitator.' L L are the pivots of agitator.

General Dscription.

'lhescoop A may be vmade of tin, sheet-iron, cop-v per, or any other suitable material, and of any rev,quired size and' shape.

The sifter B may be made of the same'material,

.and in such shape as to'b'e easily inserted in scoop A through its open bottom; and

The sieve-cloth C may be made. of fine brass or other wire, silk or other tissue or texture, as may he 'made concavous, so as to` permit the workingo'f agitator K.

A flame-work of wire, K, called an agitator, Ais suspended inside the 'scoop A by means ot' pivots, L L,

.audreaches near the stu-face of sifter B, over which 'it plays backward and forward, and thus causes the Hour or other matter to be agitated and to pass rap- A handle, H, is attached' to agitator K, and, passing upward inside of scoop through an eyelet made in the projection of the handle of the scoop, receives a spiral spring, F, and is capped with a thumb-knob,

G, screwed on its upper end, so that it may easily beV taken oft. y

The spring Fis coiled loose round handle H, between thumb-knob G and the upper side of the projection of the scoop-handle, and is intended -to put agitator K in motion.

When sitter B has been inserted inthe bottom of 4the scoop, it is firmly attached to it by means of a wire-rod, D, passingv through scoop and sitter, from one side to the other, in small holes, E E, perforated for that purpose at the 'base ofthe scoop and sifter.

The wirerod D is itself prevented from receding through theholes E E by small loopes or curves at each of its ends, turned at right angle, the one to the other.

By this means-the sifterB is easily detachable from the scoop, andmay bereplaced by similar sifters having ,liner or coarser sieve-cloth, a feature which is a great improvement on permanent sitters.

The spiral spring F being put loose ou the handle H of agitator-K, and held'in place by thumb-knob G screwed over it, may also be easily detached and replaced by a stronger-or weaker spring, according to the pressure required on agitator .K' or the strength of the hand of operator.

vThe mode of operating with the scoop and sifter is as follows:

Having scooped up the flour, meal, drug, grain, &c., required to be sifted, a pressure of the thumb on theI knob G will give the spiral'spring F the necessary recoil to cause agitator' K to play backward and forward and make the our, grain, 85e., pass rapidly through the sieve-cloth C, leaving all foreign matter and dirt inside the scoop.

. In sifting, the top ofthe scoop ought to be inclined toward the operator, iu order to bringthe sifter level, and thus have the full beuet of the sieve.

Claims.

1.- lhe scoop A', provided with a detachable siftei, B, -whereby siiters ot'diiferent degrees of ueuess may be used in connection with the scoop at will, substan' tially as described.

2. In -combination withthe combined scoop and sitter, the agitator K, having the spiral spring F ap- Dors CAMERON, J oHN WALKER MARSH.
